A typical trajectory envelope is illustrated in Figure 8.2.
To move to a different subject in the study of the vacuum trajectory, when the trajectory of
the projectile is relatively at, certain simplifying assumptions may be made, which allow the
equations of motion to be solved with greater ease. In particular, if we rewrite Equation 8.7 as
